Page 9: Graphical Leq View
Graphical LEQ View The Graphical LEQ view, allows for several different simultaneous views. On top of the four standard text readouts and phase meter, it features level bar-graphs adhering to the defined scale, while the dual Loudness bars are referring to the defined loudness scale. -
Page 10: Understanding The Basic Signal Flow Of The Dk T7
Understanding the Basic Signal flow of the DK T7 As you are probably already aware, the DK T7 is a quite complex product with a lot of different signal routing sources and destinations i.e. SDI, AES, Analogue as well as internal signal sources with destinations of Bargraphs, Text Readout, StarFish, FFT, Loudness measurement and Downmix possibilities. - Page 11 Touch the legend bar of the Bar-graph and the source selection list will open up on the right hand side of the display. Make sure to point to the specific bar-graph, that you want to alter the source for. The source selection allows you to choose between a number of Internal and External sources (see below for details on the Source list) Scroll the list to find the specific source that you are looking for.

Page 12: Label - Naming Your Input Source
Selection Menu Any input source label may be altered within each preset. The DK T7 includes a default list of typical names for faster naming, but you might also define your own. The Default Label list contains the following labels:... -
Page 13: Type Selection - Defining The Role Of Your Source
StarFish Right channel input as well as the Loudness measurement block and the Downmix module. In case the type was changed to ‘Ls’, the DK T7 would not only change inputs on the various other metering, but also make sure to compensate gain when calculating Loudness as per the BS1770 standard Loudness definition. - Page 14 If you have chosen one of these default labels, you can simply select the Type to be ‘INP’ for ‘Input’. This means that that the DK T7 will look to the Input Source Label to learn what type of signal your source is.

Page 15: Set Up Bar-Graph Options
Color Normal Each scale includes a defined ‘Peak’ level where the scale turns red. In addition to the Peak area, the DK T7 allows you to define colour of the ‘Normal’ area. The ‘Colour Normal’ sets the color of each bar-graph below the ‘Peak level’... -
Page 16: Set Up Scale & Loudness Format
The parameters in this menu counts: Scale, Under Level, Loudness Preset, Loudness Setup, Loudness Option. Scale This section allows for a choice of numerous different scales. Here is the list of scales included in the DK T7: Scale Note IEC 268 I – PPM Nordic IEC 268 IIa IEC 268 IIb –... - Page 17 Setting the window to ‘Momentary’ essentially turns the Short-term loudness reading into ‘Momentary’ loudness based on a sliding 300ms window. Please note that the DK T7 already offers the Momentary reading alongside the Short-term loudness. Reference Range: -9 and -24 dBFS (1 dB steps).
- Page 18 Range: -8 to -20 dB (1 dB steps). It is the high level parts of a program which are often of most interest for assessing compliance with broadcast criteria. To prevent an extended length of low level program content reducing the averaged loudness value to a degree that affects the measured value, the meter has an optional gating function.
- Page 19 During the Loudness capture, you may now toggle the capture between ‘Start’ and ‘Pause’. The overall resulting loudness readings will express the summarized capture of all audio above - 70dBFS from the last Reset. Hitting ‘Reset’ will re-initiate the Loudness Capture and measures. Overall, the Start-Pause mode allows you to manually start and stop the capture during breaks or audio that you do not wish to consider in the overall loudness readings.
- Page 20 Loudness measurement to go over the entire 5 minutes after every edit. With the Loudness Automation feature, the DK T7 automatically identifies what section of the audio is being altered based on the incoming time code and instantly recalculates the complete loudness result.

Page 21: Set Up Meter Text Read-Out
Hit the Text Read-out area to open up the Meter lines menu. The menu contains the settings for the four Text lines of the DK T7 display. Line 1 is always in a bigger font, while 2, 3 and 4 are small font. -

Please refer to the instrument section for further information on each of the two. Selecting Phase Correlation Sources The DK T7 allows you to freely define what two channels phase relationship is expressed by the Phase correlation meter. In order to change the Phase sources, slide to the top set of vertical buttons and hit the ‘PHSE SRC’... -
Page 23: Time-Code
Internal Time-code, incoming SMPTE time-code or off position. Incoming SMPTE code must be feed through the Right Analogue input (input2). DK T7 is capable of automating Loudness capturing based on incoming time-code, a very handy and time saving production feature. -

This may be used completely as you wish e.g. having a button strip with immediate access to the top 8 presets of the DK T7, another with Loudness Start/Stop/Reset Functions and likely one to allow switching between the different Metering Views; StarFish, Graphical LEQ, FFT and possibly a direct access to the internal Tone Generator or something completely different. - Page 25 FFT1024 Application Selects FFT View Loudness Menu Calls up the Horizontal Button set called ‘Loudness’ Preset Menu Calls up the Horizontal Button set called ‘Preset’ Main Menu Calls up the Horizontal Button set called ‘Main’ PHSE SRC Menu Calls up ‘Phase meter’...

Page 27: Loudness Automation
Loudness Automation DK T7 features a unique ability to automate and instantly recalculate Loudness results based on incoming time code. The only requirement is that you have an LTC / SMPTE time code available along with your audio signal. The benefit is a much more efficient workflow and a drastic reduction in time spent on measuring the final Loudness result. -

Setting up Moving Coils As mentioned earlier, DK T7 is capable of showing moving coil instrument emulations as opposed to the default bargraphs. Here is how to set it up: Once you have selected your sources and scale go to the folder called ‘Display Mode’... -
Page 29: Using Dk-Matrix Setup Editor
DKMatrix II is compatible with DK1, DK2, DK5 and all of the T7 models and allows for presets and setups to copied across the different models (given that they share the relevant source inputs and tools). For more information and free of charge download, please refer to DK-Technologies website. www.dk-technologies.com. -

JellyFish™ DK Technologies’ trademark ‘JellyFish®’ display was first launched on audio only meters. It was later developed to provide the alternative ‘StarFish® display and both included in the DK Meter. Both modes provide a picture of the surround audio field in 5.1, 6.1 or 7.1 channel modes. The display has the front center channel arranged towards the top with other directions are marked. -

The Loudness Capture functions are described in detail in the Capture section. The ‘Integtr’/’Shorttrm’ button allows for toggling between the two different Loudness measures. In addition to the graphical loudness, the Peak and Peak hold functions are also made available in the Graphical Loudness display. -
Page 37: Loudness & Terminology
Loudness & Terminology About Loudness Loudness measurements differ from conventional signal amplitude measurements in that they are also influenced by the frequency content of the signal and the duration of transient components. The way these various elements are handled to give a value for display has been defined by the International Telecommunications Union in their standard ITU BS1770 which is the only loudness standard to have achieve any degree of international acceptance. - Page 38 It is always the last value of the dynamic gate which is used on the material. This means that it is necessary to include or exclude any material from the “past” if the dynamic gate is changing. This means that the dynamic gate is always -10 LU under (dB relative to) the end result of the dynamic gated loudness.
